Daming Crazy Emperor

Chapter 630 The more money I spend, the happier I am
What exactly is electricity?
This is really unclear and unclear.

Because there are no electrons at all at the moment.

And Taichang is not an expert in electricity, he doesn't even major in electromechanical.

Fortunately, he still has learned basic physics, and he still remembers some experiments.

For example, the experiment of magnetic field lines.

Electrons cannot be seen without professional equipment, but magnetic force lines can be seen through a small experiment.

This experiment is actually very simple, and almost everyone in future generations will do it.

However, no one has seen or thought of it these days.

When Taichang led everyone into the temporary laboratory, everyone was still in a daze.

Glass, wood, magnet, copper wire, iron powder...

Combining these things together, it is difficult for people these days not to be confused.

What does the emperor want to do?
Taichang took a general look at the environment of the laboratory, and then solemnly said: "Yaoguang, Mizhi, doing experiments is an important means for us to study things. In the future, you must establish several professional laboratories and train a group of experimenters. It’s worth the investment.”

Seeing the serious expression on his face, everyone thought he was going to introduce what the experiment was for, but he never thought that he went to the laboratory again!

These words are somewhat inexplicable.

Everyone is a bit confused, what does it mean to invest as much as possible?
The things the emperor ordered to prepare seemed to be of little value, at most a few magnets and a few coils of copper wire were worth a little money.

All of these add up to only a few taels of silver, and the emperor actually said that it is worth the investment!

Is a few taels of silver too much for the emperor?

Cheng Jiashuo couldn't help asking: "Your Majesty, what do you need for the professional laboratory and how much will it cost?"

Without hesitation, Taichang said: "What you need is your business. As for how much money you want to invest, you can invest as much as you need, tens of thousands of taels, hundreds of thousands of taels, or even millions of taels."

Cheng Jiashuo couldn't help being dumbfounded when he heard this.

Several million taels!

What needs several million taels?
He thought that doing experiments would be like this now, just find something and try it out.

As for the experimental equipment, laboratory equipment, experimental personnel, experimental environment, etc., he has no idea at all.

Fang Yizhi couldn't help being stunned when he heard the words.

He also couldn't think of something that would cost several million taels.

Cheng Jiashuo couldn't help but asked again: "Your Majesty, do experiments really need so much money?"

When Taichang heard the words, he said thoughtfully: "As long as it is really needed, a few million taels are nothing. I will pay tens of millions of taels. The more you spend, the happier I will be!"

Perhaps, it is time to consider establishing a dedicated laboratory or research institute for these people.

As for what to study, that's too simple.

There are too many things in his mind for these people to study.

As long as the corresponding results can be produced, he will really produce tens of millions of taels!
It’s no joke that the more you spend, the happier you are, because the more you spend, the more high-end you are developing!

For example, whoever can develop a mobile phone for him, what is tens of millions of taels?

Thinking of this, he rolled up his sleeves and said, "Okay, let's do this experiment first, and we'll discuss it later and build a few research institutes."

Uh, didn't you mean a special laboratory?

Why did it become a research institute again?
Cheng Jiashuo was bewildered.

Fang Yizhi looked at the things on the big table with great interest.

Taichang directly chose a long-grinded magnet, placed it in the middle of the large table, and placed two wooden squares slightly thicker than the magnet on both sides of the magnet, and then picked up a piece of glass to cover it.

Immediately afterwards, he asked: "Mizhi, do you know why a magnet can attract iron?"

How can I know this.

Fang Yizhi shook his head without hesitation and said, "Your Majesty, the students don't know."

Taichang nodded slightly, and then solemnly said: "The reason why a magnet can attract iron is because it has a magnetic field. This experiment is to let you see what the magnetic field looks like."

After speaking, he directly scooped a spoonful of iron powder and poured it on the glass, then took the smallest wooden square and scraped lightly a few times to scrape the iron powder on the glass into a thin layer.

What the hell is the emperor doing?
Cheng Jiashuo was still dazed.

Fang Yizhi stared at the iron powder on the glass.

Immediately afterwards, Taichang said solemnly: "Look good."

After that, he took the wooden square and tapped it lightly on the glass.

A miracle happened, the iron powder on the glass slowly gathered into arcs one after another, and then ellipses one after another, and finally, it became a symmetrical shape like butterfly wings.

Taichang pointed to the pattern on the glass and said, "Mizhi, did you see that, this is the magnetic field formed by the magnet."

Fang Yizhi naturally saw this.

However, this thing is too abstract, no one can see what is going on at a glance!
Even if he is a genius, it is impossible to understand it all at once.

So, he just stared at the pattern on the glass frowning in thought, and didn't speak.

Well, it seems that we have to be more intuitive.

Taichang thought for a while, then picked up a long bar magnet of about the same size, and raised it under the glass.

It turned out that the magnet was naturally attracted with a snap.

He held two magnets that were attracted together and said to Fang Yizhi, "Do you want to know why they attract together?"

Yes I do!

Fang Yizhi nodded repeatedly: "The students want to know."

Taichang nodded slightly, then separated the two magnets, and tried to put them under the glass from both sides, until he felt that the magnetic force was almost enough, he wisely said to the other party: "Mizhi, I just did it, you can do it again." One more time, starting from scraping the iron powder."

Hearing this, Fang Yizhi quickly picked up the small wooden square, gently scraped the iron powder on the glass evenly, and then took the small wooden square to lightly tap on the glass.

His observations were not so careful, and the movements he made were similar to what Taichang had just done, without any omissions in the middle.

This time, the pattern that appeared on the glass was one corresponding arc after another, and the end of the arc happened to be the two ends of the two magnets.

Taichang immediately explained: "See, the magnetic fields of the two magnets coincide, so they will attract together."

Seeing this, Fang Yizhi couldn't help but nodded thoughtfully.

Immediately afterwards, Taichang turned a magnet around again, and then inserted it under the glass, roughly tested the repulsion force on both sides, until he felt that the repulsion force was almost enough, he wisely said to the other party: "Mizhi, do it again."

Hearing this, Fang Yizhi quickly picked up the small wooden square, gently scraped the iron powder on the glass evenly, and then took the small wooden square to lightly tap on the glass.

This time, the pattern appeared on the glass as if two magnetic fields collided, and the magnetic field lines on both sides curled backwards, and none of them overlapped at all.

Seeing this, Fang Yizhi couldn't help showing a hint of bewilderment.

Taichang then introduced: "This is the magnetic field. As long as the iron is close to the magnetic field, it will be attracted by the magnet."

Uh, there doesn't seem to be a suitable small iron block to demonstrate here.

Taichang was stunned for a moment, then said to Cheng Jiashuo: "Order someone to find some small iron nails."

Cheng Jiashuo quickly waved to an old carpenter.

Soon, the old carpenter ran over holding ordinary iron nails.

After thinking about it, Taichang stuffed another magnet under the glass, and put the other one aside.

He directly picked up the small wooden square and scratched and knocked, and the magnetic field or lines of force of the magnet appeared on the glass again.

Immediately afterwards, he picked up a small iron nail, stuffed it under the glass, and then slowly pushed it towards the magnet with a small wooden square.

At first, the little iron nail didn't react much, but as soon as it got close to the magnetic field, the little iron nail was sucked by the magnet with a whoosh.

This time, Fang Yizhi finally nodded and said: "The student understands."

well.

The next step is to use the magnetic field to generate electricity.

Taichang looked at the materials on the table, and suddenly froze again.

This seems impossible!

The materials on the table are fine, and they are enough for the experiment. The problem is that the experiment cannot be done with just these materials.

The key to using a magnetic field to generate electricity is to make the magnet or the coil rotate. If neither of these two things can rotate, it is impossible to demonstrate the use of a magnetic field to generate electricity!
